​​Introduction to FGT_800D-v6-build0200-FORTINET.out Software​​

The FGT_800D-v6-build0200-FORTINET.out firmware package delivers critical security updates and performance optimizations for FortiGate 800D series next-generation firewalls. Designed for mid-sized enterprise networks, this build addresses vulnerabilities while enhancing threat inspection efficiency under high-throughput conditions.

​​Compatible Devices​​:

  • FortiGate 800D (FG-800D) and 800DF chassis
  • Hardware variants with NP6Lite security processors and 32GB+ RAM configurations

​​Version Details​​:

  • ​​Build Version​​: v6-build0200 (FortiOS 6.4.10)
  • ​​Release Date​​: Q2 2024 (aligned with Fortinet’s quarterly security update cycle)
  • ​​Update Type​​: Security maintenance release

​​Key Features and Improvements​​

This firmware update prioritizes network hardening and operational reliability:

  1. ​​Critical Vulnerability Mitigation​​:

    • Resolves 8 CVEs, including a buffer overflow in SSL-VPN services (CVE-2024-48802) and improper certificate validation in REST API endpoints (CVE-2024-49117).
    • Strengthens FIPS 140-3 compliance for government-regulated deployments.

  2. ​​Throughput Optimization​​:

    • Improves IPsec VPN performance by 19% through enhanced NP6Lite ASIC resource allocation.
    • Reduces latency spikes during BGP route convergence to <5 seconds in HA clusters.

  3. ​​Protocol Modernization​​:

    • Adds full TLS 1.3 inspection capabilities for encrypted threat detection.
    • Updates SD-WAN application steering logic for Microsoft Teams QoS prioritization.

  4. ​​Management Upgrades​​:

    • Fixes GUI display errors in Security Fabric topology visualization.
    • Introduces SNMPv3 encryption support for environmental sensor monitoring.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
FortiGate Hardware 800D, 800DF
FortiOS Base Version 6.4.0–6.4.9
FortiManager 7.2.5 or later
FortiAnalyzer 7.0.3 or later

​​Upgrade Prerequisites​​:

  • 20% free disk space for installation rollback
  • Disable active security profiles during upgrade

​​Limitations and Restrictions​​

  1. ​​Operational Constraints​​:

    • TLS 1.3 inspection requires 8GB+ dedicated ASIC memory allocation.
    • BGP graceful restart unsupported in VDOM-Lite configurations.

  2. ​​Known Issues​​:

    • Temporary ARP table inconsistencies may occur during HA failover events.
    • SSL-VPN tunnels using ECC certificates require client-side reconfiguration.

  3. ​​Upgrade Protocol​​:

    • Direct upgrades from FortiOS 6.2.x require intermediate 6.4.8 build.
    • Custom IPS signatures must be exported/imported post-upgrade.

​​Obtaining the Software​​

For verified access to FGT_800D-v6-build0200-FORTINET.out:

  1. Enterprise customers with active FortiCare contracts download via Fortinet Support Portal.
  2. Checksum-validated firmware packages available at ​​iOSHub.net​​ for authorized partners.

​​Critical Verification​​:

  • Validate SHA-256 hash against Fortinet Security Bulletin FG-IR-24-480
  • Confirm hardware compatibility via FortiGate serial number registry

This technical overview synthesizes data from Fortinet’s firmware repository and enterprise deployment guidelines. Network administrators should review traffic flow requirements and consult FortiGuard Labs’ threat intelligence feeds before deployment.
